Read： 972 Time：12months ago Source：Transform the World with Simplicity

Vinyl acetate is an important organic chemical raw material, widely used in polymers, coatings, adhesives, textiles and other fields. This article will detail the properties and uses of vinyl acetate.

1. the properties of vinyl acetate

vinyl acetate is a colorless and transparent liquid with a pleasant smell. It is flammable, and steam and air can form explosive mixtures. Vinyl acetate has a melting point of -93.2°C, a boiling point of 72.2°C and a density of 0.932g/cm³. It is insoluble in water, but soluble in alcohol, ether, acetone and other organic solvents. Vinyl acetate is chemically active and prone to polymerization.

2. the use of vinyl acetate

1. Polymer production

vinyl acetate is the main raw material for the production of polyvinyl acetate (PVAc). Polyvinyl acetate is a thermoplastic polymer with good chemical resistance, oil resistance, water resistance, weather resistance and electrical insulation, and is widely used in the production of glue, coatings, textile processing and so on.

2. Coating and Adhesive

Vinyl acetate can be used to produce a variety of coatings and adhesives. It is an emulsion coating made by copolymerization with other monomers, which has good weather resistance, water resistance, scrub resistance and decoration, and is widely used in construction, furniture, automobiles and other fields. In addition, vinyl acetate can also be used in the production of woodworking adhesives, paper adhesives, etc.

3. Textile processing

Vinyl acetate can be used in textile processing to improve the elasticity, softness and abrasion resistance of fabrics. It is a textile finishing agent made by copolymerization with other monomers such as acrylic acid, which can give the fabric excellent performance.

4.

in other fields Vinyl acetate can also be used to produce plastic plasticizers, stabilizers, antistatic agents, etc. In addition, it can also be used in the manufacture of spices, pharmaceutical intermediates, etc.

In conclusion, as an important organic chemical raw material, vinyl acetate has a wide range of applications in polymers, coatings, adhesives, textiles and other fields. With the continuous development of science and technology, the application field of vinyl acetate will continue to expand.
